Is my script causing prevent me to test out my games in studio?

Every time I wanted to test out my game it simply just stops at 33%, i'm not sure if its my scripts causing the studio to bugging out.

#Script1_BanService

--start of script

local sservice = game.ServerScriptService

if script.Parent ~= sservice then 
	script.Parent = game.ServerScriptService
end

--wait() can screw banservice check

local Bstat = game:GetService("DataStoreService"):GetDataStore("BanService_1")
local Wstat = game:GetService("DataStoreService"):GetDataStore("BanService_1")
local Rstat = game:GetService("DataStoreService"):GetDataStore("BanService_1")

--create ui message when ban/warning is  true

--[[
local ReasonMessageValue = Instance.new("StringValue")--finish this man
local storedDatas = Instance.new("Folder")
storedDatas.Parent = game.ServerScriptService
ReasonMessageValue.Parent = storedDatas
ReasonMessageValue.Value = "nil"
ReasonMessageValue.Name = "Value"
]]-- Waste of time, idea discarded

--function sendval()
--end


--function sendtoui()
--end

game.Players.PlayerAdded:connect(function(player)
	local Banned = "user_" ..player.userId
	local Warning,Reason = "user_" ..player.userId
	if Bstat:GetAsync(Banned) == 1 then
		ReasonMessageValue.Text = ReasonMessageValue
		kick()
	end
end)

I had something similar happen to me. My problem was that i didn't have wait() in the script, and this apparently made the studio freeze when i tried to test.

while true do
	--wait() was missing
	--some other codes
end

Maby try this:

if script.Parent ~= sservice then 
	wait() --try to add this and see if that helps
	script.Parent = game.ServerScriptService
end

Alright, first of all, userId is deprecated, use UserId instead, also you should be using Connect instead of connect.

--start of script

local sservice = game.ServerScriptService

if script.Parent ~= sservice then 
    script.Parent = game.ServerScriptService
end

--wait() can screw banservice check

local Bstat = game:GetService("DataStoreService"):GetDataStore("BanService_1")
local Wstat = game:GetService("DataStoreService"):GetDataStore("BanService_1")
local Rstat = game:GetService("DataStoreService"):GetDataStore("BanService_1")

--create ui message when ban/warning is  true

--[[
local ReasonMessageValue = Instance.new("StringValue")--finish this man
local storedDatas = Instance.new("Folder")
storedDatas.Parent = game.ServerScriptService
ReasonMessageValue.Parent = storedDatas
ReasonMessageValue.Value = "nil"
ReasonMessageValue.Name = "Value"
]]-- Waste of time, idea discarded

--function sendval()
--end


--function sendtoui()
--end

game.Players.PlayerAdded:Connect(function(player)
    local Banned = "user_" ..player.UserId
    local Warning,Reason = "user_" ..player.UserId
pcall(function()
    if Bstat:GetAsync(Banned) == 1 then
        ReasonMessageValue.Text = ReasonMessageValue
        kick()
end)
    end
end)

Still stuck at 33%. I've rewritten the script with no errors and bugs and my studio stops at 33% when testing
